To all whom it may coaoera':

Be it known that I, HENRY R. WAnFORD, a citizen of the United States, residing at Memphis, in the county of Shelby and Stater of Tennessee, have inventedcertain new and useful Improvements in Rerailing Frogs, of which the following is a full,` clear, and exact description, such as-will enable anyone skilled in the art to make and use the same. Y A

-This invention relates to devices which will facilitate the rerailing of de-railed railway rolling stock. It relates more specifically to a rerailing frog which will rest on and engage the rail of a track to support one end of the frog and insure against lateral movement of the frog while a car is being moved thereover; which will rest on and solidly engage thetie to prevent longitudinal displacement; which will engage the rail to prevent vertical movement; and which will provide a broad base to prevent over-turning.

-The objects of my invention are,

First, to make a frog which is adapted for use on either the inside or outside of the rail and is usable for'replacing rolling stock from either direction.

Second, to make a frog one end of which will rest solidly upon the rail and be there held against lateraldisplacement, and the Y other end of which will rest solidly on a tiel and so abutl against same as to be held against longitudinal displacement.

Third, to make la frogV which will be braced against overturning.

Fourth, to make a frog which will lock Abeneath the ball of the rail and be prevented thereby from vertical displacement.

I accomplish these objects as will bemore fully hereinafter set out kin the drawings, `specification and claims. j j

In the drawings:

Fig. l is a side elevation of the rerailing frog as applied to one of the rails of the track. I Fig. 2 is a plan View of the frog shown in Fig. 1.

Fig. s is a Section on the une Iii-III of Fig. 1 showing the means for locking the rerailing frog against vertical displacement.

Fig. 4 is a section on the line IV-IV of Fig. 2 showing the manner in which the f .end of the frog engages the rail.

Referring now to the drawings in whichv the various parts are indicatedr by numerals.

1-l are railroad ties, 2 are tie plates there-y on and 3 railroad rails resting on theptie plates, the customary spikes for Y fastening the rail to theA tie not being shown. Y

The frog comprises a member substantially of rectangular cross section symmetrical about its transverse center. The top 4 is avk plane surface with downwardly, curved ends surfaces 5 forming approaches.

The rfrog is of greatest depth at thev center 6 from which point the under surfaces 7` converge similarly toward the top 4. The curvature I of the upper surface of the ends until it y passes beyond the plane of 'the undersurface and the end 8 itself is eXtend ed below these undersurfaces and substantially at right angles to them to provide tie abutments adapted tok come against the sides of the ties.

9 are laterally projecting lugs or members disposed one near each end, each of which members with the underside of the' the plan View Fig. 2.V Y

The undersurfaces 7 of either end are disposed at such angle to the top 4 and the seat 10- thatrwhen the seat 10 at one end rests on the top of a rail the opposite-undersurface 7r formsa seat adapted to rest on vthe tiel and support that end of the frog. This supporting surface is broadened by laterally e projecting flanges y12 the` undersides vof is continued rog as shown by the dotted lines 11 in which are flush with and form an extension of the surfaces 7.

13 is a dog adapted to engage the under`l sidel 14 of the ball` of the rail and to lock into the corner formed by the ball of the rail and the web 15 thereof. This dog preferably comprises a bolt 16 having a sleeve nut 17 thereon with a pointed end 18, Awhich nut may be screwed out to `engage the rail.

portion to form tie abutments for said frog; a member projecting laterally from the side of the body portion near each end, having an angularly disposed channel-Way out therethrough and through the said ends to provide a rail seat; and flanges, oppositely disposed from said members, extending laterally from said body portion and having their under surfaces flush with the under surface of said body a continuation thereo portion and forming 10 to form, With .the

underside of said body portion, a tie seat for said frog.
